Self-cleaning fabrics have been successfully prepared by depositing and grafting TiO2 nanoparticles, and silane coupling agent 3-Aminopropyltriethoxysilane was adopted to improve the photocatalytic activity of self-cleaning fabrics. TEM results showed that the treatment of silane coupling agent is good for increasing the amount of TiO2 particles. The excellent photocatalytic activity of TiO2-coated cotton fabrics is attributed the increase of TiO2 particles and the formation of the TiO2/SiO2 structure.

In this work, a comparative study of the photocatalytic activity of synthetic titanosilicate powders with differences in phase composition and specific surface area was carried out. Evaluation of the efficiency of decomposition of the dye methylene blue in the presence of titanosilicate additives in an aqueous medium under ultraviolet and visible light sources is given. The self-cleaning ability of titanosilicate-modified cement stone was studied by exposure to ultraviolet and visible light using ImageJ software. The strength of a cement stone modified with a titanosilicate additive has been determined, and its ability to self-cleaning under the influence of ultraviolet and visible light has been studied.

In the study the self-cleaning properties of photoactive gypsum plasters are presented. The modified gypsum plasters were obtained by addition of 1 and 3 wt.% of nitrogen-modified titanium dioxide (TiO2/N) and 0.1, 0.3, and 0.5 wt.% of glass fiber. The self-cleaning ability of the obtained materials was tested during two dyes decomposition: Methylene Blue (MB) and Reactive Orange (RO). It was found that presence of glass fiber increased photocatalytic activity of modified gypsum plasters, which may be due to the fact glass fiber may act as ducts for light and transport it to sites screened by TiO2 or glass fiber can retard charge recombination. Moreover, unexpectedly the addition of glass fiber did not increase the mechanical properties of modified gypsum plasters, which may be because gypsum does not strongly adhere to the surface of glass fibers.

Nonthermal plasma processing is a dry, environment-friendly and chemical-free method of improving the wettability, adhesion, self-cleaning and dying quality of fabrics without affecting their bulk properties. This study presents a green synthesis and coating method for the immobilization of nanoparticles of ZnO on the nonthermal plasma functionalized cotton fabric. The self-cleaning activity of ZnO-coated cotton was then optimized statistically. The ultraviolet protection and antimicrobial activity of the optimized and a control sample were also elaborated in this study. Psidium guajava Linn (guava) plant extract and zinc chloride were used in the ultrasonic biosynthesis of ZnO nanoparticles and concurrent immobilization over plasma functionalized cotton. Sodium hydroxide was used as a reaction accelerator. Statistical complete composite design (CCD) based on the amount of ZnCl2, NaOH and plasma exposure time was used to optimize the role of input parameters on the self-cleaning ability of the coated cotton. Methylene blue in water was used as a sample pollutant in the self-cleaning study. The ZnO-coated cotton showed notably high self-cleaning activity of 94% and a UV protection factor of 69.87. The antimicrobial activity against E. Coli and S. Aureus bacteria was also appreciably high compared to the control.
